Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583192, here are decompositions:

61 + 31583131 = 31583192
211 + 31582981 = 31583192
241 + 31582951 = 31583192
373 + 31582819 = 31583192
463 + 31582729 = 31583192
661 + 31582531 = 31583192
859 + 31582333 = 31583192
1009 + 31582183 = 31583192

Showing the first eight; more decompositions exist.
